  • You know, yesterday there was some excitement when crews put down what is called a geophone, Tony.

  • Their "geophone" essentially serves that purpose, though I had to wonder why it took them so long to think about it.

    undefined

  • Some of these feature the rarely used geophone, a percussion instrument—invented by Olivier Messiaen for his "From the Canyons to the Stars"—that consists of an oil drum filled with dirt pellets.

  • I knew that seismologists used a geophone to measure earthquakes, which worked pretty much like a condenser microphone with a magnet and coil.

  • This simple action allowed us to measure the time it took for the wave produced by the sledgehammer to reach the geophone or to pass between geophones.

    The Elephant's Secret Sense

  • We had painstakingly measured out each geophone from the head of the trough with the DGPS, providing the centimeter accuracy needed in our distance calculations.

    The Elephant's Secret Sense

  • Excited by this goal, we decided to run a geophone off the tower at a 50-yard distance and collect data from footfalls for the rest of the field season.

    The Elephant's Secret Sense

  • We recorded rumbles using microphones to measure how far and how fast the elephant vocalizations traveled in the air, and then a similar recording device, a geophone, to measure vibrations in the ground.

    The Elephant's Secret Sense

  • We hoped to model how far the rumbles could travel, given the strength of the rumbles at the most distant geophone, and the fall-off rate between sensors.

    The Elephant's Secret Sense

  • Have you heard anything to that effect, that they are essentially trying to find them, trying to find where they are, you dig the borehole, you drop the geophone down for some kind of sound, some kind of proof of life?
